IMPROVEMENT IN CHURNS.

4 The Schedule'referred to in these Letters Patent and making paz-tof the same.

To all 'whom it ma/y concern:

Be it known that I, JOSEPH L. MARSH, of Gentreville, in the county of AWayne,`and. State of Indiana, have invented a new and useful Improvement in Ohurns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making 4part of this specification, in which- Figure 1 is a -vertical elevation of my invention, showing it as applied to an ordinary churn.

Figure 2 is a plan view, showing the dasher, and the relativepositions lof the revolving, to the stationary parts.

Corresponding letters refer to corresponding parts in the figures.

This inventionrelates to an improvement in ch-urus and It consists in a removable dasher or agitator,to be placed in any cylinder-churn, one portion of which is stationary, and another portion of which is arranged to rotate within said stationary-parts, as will be more fully described. hereafter.

A, in the drawings, represents a vessel, of cylindrical form, which is adapted for the reception of my improved dasher or agitator.

B Brepresent avframe, which consists of two or more vertical portions, which at their lower ends are secured to a horizontal plate or platform.

. rlhis frame is to be of such dimensions as that the circumference of its vertical portions will fill the vessel into which it is desirable to place it, and tit so tightly therein as to retain it in its position while in use.

The vertical portions of the frame, in their crosssections, are to occupy a position at an angle with a line drawn through the axis of the device, as shown clearly in fig. 2 of the drawings; the object of this being to present a sharp edge for the butter-globules contained in the milk, to come in contact with, as it is forced past those parts, by the action of the revolving portionof thev dasher or agitator; as a consequence of which, such globules will be effectively broken,`and the butter contained therein allowed to unite with other portions in forming a mass, such as is the re sult of churning by all methods.

These portions of the agitator are also to be furnished with a row or series of perforations near their inner edges, which are designed to further facilitate the operation of breaking `the globules, as above described. 4

G represents that portion of the agitator which is to rotate Within the space leftl between the vertical portions.

This agitator is bevelled or rounded Aupon its edges, as shown in iig. 2, and'is to be secured to a shaft, D, which is to be stepped in the bottom plate of frame B B, and extend upward to and above the top of the vessel which contains the agitator, so that a bevelled wheel, E, may be placed thereon, to mesh with a sim- -ilar one which may be secured to the top of such vessel,

and by which the wheel E, shaft D, and agitator C may be rotated.

It is apparent, that if found desirable, a series of apertures, corresponding with those in the stationary `now in use.

Having thus 'described my invention, What I claim, and desirel t'o secure by Letters Pat- The constructionof the removable portions B B and O C, as and for the purpose s'et forth.

In testimony whereof', I have signed my name toA this specification, in the presence of two subscribing witnesses.
